Sleeping

My girlfriend started falling asleep during sex. Disconcerted, I asked her whether I should be doing it differently or something. She told me everything was fine and that I wasn't to worry, but it kept on happening. Once, I shook her awake and begged her to tell me what it was she really wanted me to do. "Oh, you wouldn't want to know", she laughed. I told her I wanted to know more yhan anything in the world; that I could think of little else. She looked away. "No, really", she said quietly almost to her self. "You wouldn't want to know."
